These could all be old codes and you're just getting freaked out because you're hitting fuel cut and possibly over boosting. What's your AFR when the engine freaks and what is the boost reaching?
An O2 sensor wouldn't cause any of this, the ECU doesn't reference it at high loads.
And no, like Frisbee said, don't replace the knock sensor... see aren't you glad you stopped dicking around?  |
i think i misinterpreted code 44, i only saw it once and i stood there for about 10mins, making sure i noted down the right codes. I don't know my AFR because i haven't installed the a/f gauge. The boost gauge is no longer working but when it was, it climbed over the 8+ mark and i was barely on the throttle, when i opened the throttle a little more, that is when i got the jerking action. Its definitely making more boost due to the bigger exhaust, i felt that from the start.
i was planning on upgrading my fuel system by a shop called e-shift performance. A guy that i know, who own an MKIV, told me that shop would get my supra up to par...as far as sensors and maintenance, what should i do? Should i get new sensors to replace the sensors that have reported error codes?
